  ADVANTAGE OF THE INVENTION According to this invention, the cosmetics from which sufficient cosmetic effect is acquired even if the compounding quantity of a human oligopeptide is small can be provided.

Hereinafter, preferred embodiments of the cosmetic and the production method thereof according to the present invention will be described in detail.
<Cosmetics>
First, the cosmetic of the present invention will be described in detail.

  The cosmetics in this specification include skin cosmetics and hair cosmetics, and specifically include lotions, milky lotions, creams, packs, shampoos, rinses, facial cleansers, body soaps, hair styling agents, hair tonics. Etc.

  The cosmetic of the present invention contains human oligopeptide and Sphingomonas extract.

[Human oligopeptide]
Human oligopeptide is a kind of protein, called “cell regeneration factor”, and is a factor inherent in humans. This human oligopeptide is a component having a function of promoting the production of new cells by binding to receptors on the surface of the skin. It is said that when this human oligopeptide is reduced by aging, the skin cell regeneration function is lowered, and skin aging such as spots, wrinkles and sagging proceeds.

  If such a human oligopeptide can be sufficiently supplied to the skin, the effect of preventing skin aging can be expected.

  However, this human oligopeptide is a very expensive component, and there is a problem that if a large amount of human oligopeptide is blended in order to sufficiently supply it to the skin, the cosmetic becomes very expensive. In order to avoid this problem, if the blending amount of the human oligopeptide is reduced, there is a problem that the above-described effects cannot be obtained sufficiently.

  On the other hand, in this invention, sufficient cosmetic effect can be acquired even if the compounding quantity of a human oligopeptide is small by mix | blending a human oligopeptide and Sphingomonas extract which are mentioned later. This is because Sphingomonas extract has a function of activating the above-described functions of human oligopeptides, and thus exhibits a sufficient anti-aging effect even if the amount of human oligopeptides is small. Conceivable.

  Examples of human oligopeptides include epidermal growth factor (EGF), fibroblast growth factor (FGF), vascular endothelial growth factor (VEGF) and the like. Of these, one or two or more can be used in combination.

The compounding amount of the human oligopeptide is preferably 1 × 10 ^{−9 to} 1 wt%, and more preferably 1 × 10 ^{−8 to} 0.5 wt%. Even with such a small blending amount, the cosmetic of the present invention can exhibit an excellent feeling of use and an excellent cosmetic effect. On the other hand, if the blending amount of the human oligopeptide is less than the lower limit, a sufficient cosmetic effect may not be obtained depending on the blending amount of the sphingomonas extract described below. Moreover, when the compounding quantity of a human oligopeptide exceeds the said upper limit, cosmetics will become expensive.

[Sphingomonas extract]
Sphingomonas extract is a mixed lipid of glycosphingolipids and phospholipids obtained from cultured sphingomonas cells called fermented ceramides.

  This sphingomonas extract is a component that has a function of retaining moisture in the cells (humidity retaining function) while connecting gaps between the corneocytes and preventing the entry of oxygen and stimulants.

  Sphingomonas extract is a component having a function of activating the function of the human oligopeptide as described above. Thereby, by using together with the said human oligopeptide, cosmetics will have the outstanding cosmetic effect.

When the blending amount of human oligopeptide is X [wt%] and the blending amount of Sphingomonas extract is Y [wt%], the relationship of 1 × 10 ⁻⁴ ≦ Y / X ≦ 1 × 10 ¹⁰ is satisfied. It is preferable that the relationship of 2 × 10 ⁻³ ≦ Y / X ≦ 1 × 10 ⁸ is satisfied. By satisfying such a relationship, the function of the human oligopeptide can be more effectively activated while sufficiently exerting the effect of blending the sphingomonas extract.

Specifically, the amount of Sphingomonas extract is preferably 1 × 10 ^{−4 to} 10 wt%, and more preferably 1 × 10 ^{−3 to} 1 wt%. Thereby, the function of a human oligopeptide can be activated more effectively, fully exhibiting the effect by mix | blending Sphingomonas extract.

[Other ingredients]
The cosmetic of the present invention may contain, for example, hyaluronic acids, collagen, elastin and the like in addition to the above components.

(Hyaluronic acids)
Hyaluronic acid is a kind of glycosaminoglycan (mucopolysaccharide) and is a component having a very high moisturizing power. In the present invention, hyaluronic acid refers to hyaluronic acid, hyaluronic acid derivatives and salts thereof.

  By including such hyaluronic acid (hereinafter also referred to simply as hyaluronic acid), the hyaluronic acid supplements the skin (skin cells) with water, and the sphingomonas extract connects the keratinocytes and prevents oxygen and stimulants from entering. It can be surely prevented. Moreover, moisture can be retained in the cells for a longer time due to the synergistic effect of the moisturizing effect of hyaluronic acid and the moisturizing effect of Sphingomonas extract.

  Furthermore, by including hyaluronic acid, the human oligopeptide can be supplied more reliably in the cell, and the effect of including the human oligopeptide can be made more remarkable.

  As such hyaluronic acids, it is preferable to use a salt of hyaluronic acid or a salt of a hyaluronic acid derivative from the viewpoint of ease of handling.

  Moreover, as hyaluronic acid, it is particularly preferable to use acetylated hyaluronic acid or a salt thereof. Acetylated hyaluronic acid or a salt thereof has a particularly high water-holding power (moisturizing power) compared to other hyaluronic acids, so that the effects of including human oligopeptide and sphingomonas extract are more remarkable. can do.

The blending amount of hyaluronic acid is not particularly limited, but is preferably 1 × 10 ^{−5 to} 10 wt%, and more preferably 1 × 10 ^{−4 to} 1 wt%. Thereby, the feeling of use and the beauty effect can be made particularly excellent.

(collagen)
Collagen is a kind of protein constituting dermis, ligament, tendon, bone, cartilage and the like, and is a component having a moisturizing function. By including such collagen, it is possible to activate the collagen-producing ability inherent in humans and improve skin metabolism.

  The collagen used in the present invention is not particularly limited. For example, fibrous collagen such as type I-III collagen and type V collagen, type IV collagen, non-fibrous collagen such as type VI-VIII, or these Examples include hydrolyzed collagen (collagen peptide) obtained by hydrolyzing collagen with an acid or enzyme, water-soluble collagen (atelocollagen), and the like. Among these, it is particularly preferable to use hydrolyzed collagen.

  Hydrolyzed collagen is a component having a low molecular weight (average molecular weight of 5000 or less) and a molecular size of nano-order. Hydrolyzed collagen is a water-soluble component. For this reason, the permeability to the skin is high, the collagen can reach the deep layer of the skin, and the collagen can be efficiently absorbed into the skin cells. As a result, various effects of collagen on the skin can be efficiently exhibited.

  Moreover, absorption of such a human oligopeptide to the skin can be promoted by including such hydrolyzed collagen. This is probably because hydrolyzed collagen and human oligopeptide have high affinity, so that human oligopeptide also permeates into the skin as hydrolyzed collagen permeates into the skin. As a result, the skin regenerating function can be further improved, and a cosmetic material with excellent cosmetic effects can be obtained.

Although the compounding quantity of collagen is not specifically limited, It is preferable that it is 1 * 10 < ^-5 > ^-10 wt%, and it is more preferable that it is 1 * 10 < ^-4 > -1 wt%. Thereby, the feeling of use and the beauty effect can be made particularly excellent.

(Elastin)
Elastin is a fibrous protein that works extracellularly like collagen, and has a property (elasticity) that expands and contracts like rubber, and is a component that gives skin tissue flexibility. Elastin is widely distributed in organs that require elasticity such as the dermis, ligaments, tendons, and blood vessel walls of the skin, and the decrease in elastin due to aging causes wrinkles and sagging.

  By including such elastin, the elasticity and firmness of the skin can be improved more effectively.

  The elastin to be blended is not particularly limited, and for example, water-soluble elastin, hydrolyzed elastin and the like can be used. Among them, it is preferable to use hydrolyzed elastin hydrolyzed with an enzyme or the like. Hydrolyzed elastin is a low-molecular weight, water-soluble component similar to the above-described hydrolyzed collagen. Therefore, the permeability to the skin is high, elastin can reach the deep layer of the skin, and elastin can be efficiently absorbed into the skin cells. As a result, various effects of elastin on the skin can be efficiently exhibited. Moreover, it has the effect of promoting the penetration of human oligopeptides into the skin, similar to the above hydrolyzed collagen.

  In addition, hydrolyzed elastin has a protective colloid action and can be expected to have an effect of protecting and improving the skin. Furthermore, the moisturizing effect by each of the above components can be maintained by the protective colloid action.

Although the compounding quantity of elastin is not specifically limited, It is preferable that it is 1 * 10 < ^-5 > ^-10 wt%, and it is more preferable that it is 1 * 10 < ^-4 > -1 wt%. Thereby, the feeling of use and the beauty effect can be made particularly excellent.

The cosmetic of the present invention may contain a polyhydric alcohol in addition to the above components.
The polyhydric alcohol has a moisturizing function and a viscosity adjusting function.

  The polyhydric alcohol is not particularly limited. For example, glycerin, diglycerin, polyglycerin, polyglycerin, 1,3-butylene glycol, polyethylene glycol, 1,2-pentanediol, 1,3-hexanediol, propylene glycol. , Dipropylene glycol, isopropylene glycol, polypropylene glycol, ethylene glycol, polyethylene glycol, diethylene glycol, polyethylene glycol, triethylene glycol, polyethylene glycol, maltitol, reduced starch syrup, lactitol, palatinit, erythritol, sorbitol, mannitol, xylitol, xylose, Trehalose, glucose, glucose, lactose, mannose, maltose, fructose, inosito Le, pentaerythritol, maltotriose, starch degradation sugars, starch decomposing sugar reduced alcohol and the like, among these, can be used alone or in combination.

  The blending amount of such a polyhydric alcohol is preferably 0.01 to 40 wt%, and more preferably 0.1 to 30 wt%.

  In addition to the above-described components, the cosmetics of the present invention can be blended with commonly used base components and medicinal components depending on the purpose and dosage form.
